RFID Tags

Radio Frequency IDentification (RFID) tags have been proven to be the most efficient way of monitoring and controlling visitors on secure premises.

Tensor smart cards are issued complete with an embedded RFID tag allowing all visitors, contractors and staff to securely move around onsite and only access pre-defined areas if they have been granted specific permission.

RFID tags include a chip that typically stores a static number (an ID) and an antenna that enables the chip to transmit the stored number to a reader.

When the RFID tag comes within range of the appropriate smart card reader, the tag is powered by the reader's 125 KHz electromagnetic field enabling it to transmit its ID. The reader has two read bands within this field; an inner and outer band, and these are controlled and rapidly oscillated by the reader's on-board microprocessor.

With up to 34 billion different combinations of ID number, there is no chance of duplication. In addition, each smart card has built-in security and integrity checks powered by embedded software and hardware, thus ensuring that the card cannot be misread or tampered with in any way.

Smart cards can also be quickly branded with a photograph of the owner, printed out by a magicard printer attached to the visitor monitoring system. This creates a secondary means of identification and can verify the cardholder's identity in seconds.

In addition to visitor monitoring, RFID tags are used in a wide range of applications such as: identifying animals, tracking goods through the supply chain, and controlling access into buildings.
